This reverts commit 906450e2.

1) It was a quick debug hack 2) it doesn't meet the requirements
for changing extlib/ libraries

Cleanup for memcached host/port split -- apparently we use ';' on purpose, restoring. Keeping fix for the notices spewing into the log.

Fix for background recalculation of groups; needs to get Group objects not IDs; also don't list any groups for repeats to match saveGroups behavior
todo: merge calculation portion with saveGroups so they don't get out of sync

Fix since_id and max_id API parameters for inbox-based loads; was failing if the exact id mentioned wasn't present in the inbox (or had been trimmed out)

temporary --skip-xmpp flag on queuedaemon.php, allows to run queue daemons but skip subscription to xmpp-based queues
(still working on making these behave gracefully when server is down)

Clean up host/port separation in memcached plugin -- use : not ; as separator and clean up some warnings
